Metallics JDS81SS – Frequently Asked Questions

1) Can I use these stainless screws to fasten into aluminum?
You can, but watch the corrosion. Driving 18-8 stainless into aluminum or steel can set up a galvanic couple in some environments, which attacks the softer base metal around the fastener. Outdoors, in coastal air, or anywhere that stays wet, isolate the joint or pick a fastener closer to the base metal electrochemically. Dry indoor work is generally not a problem.
2) Is a #10 x 3 inch Type A tapping screw the right fastener for sheet metal, or do I need a self-drilling screw?
A Type A tapping screw like the JDS81SS has a gimlet (sharp) point and 12 threads per inch, coarse spacing meant for thin sheet metal, and it needs a pilot hole punched or drilled first. It does not cut its own hole. If you want to go straight into the metal without pre-drilling, you want a self-drilling screw with a drill-point tip instead. At 3 inches long, this one is sized for going through thick material or standoffs into a thin metal substrate.
3) Does the Metallics JDS81SS have a built-in washer under the head?
The head is an indented hex with an integral washer face. Washer OD measures 0.384 to 0.414 inch and washer thickness 0.019 to 0.031 inch, with head height 0.105 to 0.12 inch. That bearing surface spreads the load on sheet metal, so you do not need to add a separate flat washer unless you are spanning an oversize hole.
4) How are these tapping screws packaged and what is the minimum I can order?
Metallics supplies the JDS81SS in a jar, with a 100 count minimum order. Shipping weight on that jar is 1.83 lbs. Other sizes and quantities are available by request.
5) What standards do these #10 indented hex head tapping screws conform to?
Head dimensions follow ASME B18.6.3-2010 and the thread conforms to ASME B18.6.4. One caveat worth knowing if you are standardizing a spec: Metallics notes that dimensions for the #9 diameter are independent of ASME B18.6.4. The #10 x 3 inch JDS81SS itself is covered by those standards.
6) Do these Metallics screws meet Buy American and ARRA requirements for a federal job?
Metallics flags the JDS81SS as compliant for both Buy American and ARRA purposes. Country of origin on the part is China. If your contract language is strict domestic-melt rather than ARRA-style compliance, verify against the clause in your spec before you commit the submittal.
7) Are these screws hard enough to thread into steel, or will the heads strip?
Case hardness runs Rockwell C28-38, which is the hardness range used for tapping screws that need to form threads in sheet metal without the point rolling over. Pair that with a correctly sized pilot hole and the 5/16 hex head drives without camming out, which is the practical advantage of the hex over the slot alone.
